Environmental Services in Prince George's County, MD

Maryland does not universally mandate a Phase I by statute for all transfers, but lender requirements, MDE's Voluntary Cleanup Program eligibility review, and certain county-level approvals effectively make ASTM E1527-21 Phase I documentation standard practice. Brownfield-related tax credit applications through the state also typically require a qualifying environmental professional's assessment consistent with E1527-21 before MDE will engage on a cleanup plan.

Legacy dry cleaners, auto service, and bulk fuel operations are common along older commercial corridors and frequently leave chlorinated solvent or petroleum hydrocarbon impacts in shallow soils and groundwater. Phase II scope under ASTM E1903-19 would typically include soil borings, groundwater monitoring points, and laboratory analysis targeting the recognized environmental conditions identified in the Phase I — with boring locations driven by site history and prevailing groundwater flow direction.

Coastal Plain soils in lower-elevation portions of the county can produce seasonally shallow water tables, which affects both boring advancement and groundwater sampling representativeness. We factor seasonal groundwater trends into boring depth selection and, where appropriate, recommend sampling during periods of seasonal high water to capture worst-case conditions for contaminant transport — a consideration MDE reviewers sometimes raise during voluntary cleanup program submittals.
